FUEL-CHARGING DEVICE.

Application filed December 18, 1923.

To all whom it may concern:

Be it known that I, DANIEL J. YoUNe, a citizen of the United States ofAmerica, residing at Tacoma, in the county of Pierce and State ofWashington, have invented certain new and useful Improvements inFuel-Charging Devices, of which the following is a s ecification.

The invent1on relates to fuel charging devicesfor gas producers or otherfurnaces in which it is desirable that the fuel be distributed uniformlyover the entire surface of the fire-bed instead of being delivered in aheap at the center.

An important object of the invention is to provide an improved chargingdevice which will secure such uniform distribution and which will beentirely gas tight even when the fuel is being delivered to theproducer. A further object is to provide a charger which is notdependent on the presence of fuel to render it gas tight, the parts ofthe device being so assembled that no leakage is possible. Anotherobject of the invention is to provide a fuel charger consisting ofsuperposed annular members having their axial openings in alignment,whereby a central opening for initially charging the furnace isprovided, and having also eccentric openings through which uniformdistribution of fuel may be secured when the furnace is in operation.Another object is to provide a fuel leveling device or plow for use incon nection with feeding the improved charging mechanism.

Other objects will be apparent from the accompanying detaileddescription and the appended claims.

Referring now to the drawings in which is shown an illustrativeembodiment of the invention,

Fig. 1 is a central vertical section of the upper part of a gas produceror the like shown as provided with the improved charging device.

Fig. 2 is a plan view on a reduced scale showing the superposed annularcharging members which constitute the main features of the invention.

Fig. 3 is a detail sectional view showing a ring member which rests uponthe top of the gas producer and to which the charging mechanism properis secured.

Fig. 4 is a detail plan view showing the lowest of the three annularcharging members.

Serial No. 681,341.

Fig. 5 is a vertical sectional view of the same.

Fig. 6 is a plan view of the rotatable intermediate charging member.

Fig. 7 is a vertical sectional view of the same.

Fig. 8 is a plan view of the upper annular charging member, and

Fig. 9 is a vertical sectional view of the same.

Referring particularly to Fig. 1, the reference numeral 10 denotes thewall of gas producer or furnace of any desired construction upon whichthe improved charging device is mounted. It will be noted that the fuelbed 11 is of nearly uniform depth.

A simple means for mounting the fuel charger is provided which permitsit to be used with any kind of producer, furnace or the like. As shown,a ring 12 (see Fig. 3) rests upon the top of the producer and isprovided with upper and lower outwardly extending flanges 13 and 14 andwith an inwardly extending flange 15. A liner 16 is suspended from theflange by means of a flange 17.

As shown, the fuel charger comprises three superposed annular members orrings 18, 19 and 20, the upper and lower of which are fixed, while theintermediate ring 19 is rotatable relative thereto. The three membersare provided with co-axial openings forming a single central chargingopening 25, through which fuel may be initially fed directly .into theinterior of the producer. In addition to the central opening, each ringhas a plurality of eccentric openings through which fuel is distributedinto the producer during operation, of the same.

As shown, the charging member 18 rests upon the flanges 17 and 13 of theliner 16 and ring 12 respectively and is secured to the flange 13 bymeans of bolts 21. The lower ring 18 may be water-cooled as indicated at22, water being admitted at 24:. A collar 26 on this lower member linesthe central opening 25, over which asuitable cover plate 27 may benormally secured.

Any suitable clamping means for the plate 27 may be employed. As shown,a cotter bar 28 and T-screw 29 are employed, the threaded portion of theT-screw being screwed into the bar 28 and plate 27. Bolts 30 (Fig. 2)passing through the ends of the cotter bar are threaded into the collar26, whereby the cover plate 27 may be firmly I gularly displaced fromthose of the upper 1 below it.

ring to prevent the passage of fuel directly from the outside to theinside of the fur nace and to prevent the escape of gas from theproducer. The rotatable intermediate ring 19 is provided with openings34% equal to in number or greater or less in number than the openings inthe upper and lower charging rings. Preferably, the openings in therings 18, 19 and 20 are so arranged that but one pair of openings inadjacent rings can be brought into registry at one time.

. It will be further noted that the successive charging members 18, 19and 20 are provided withannular flanges and grooves, the flange on eachupper member fitting into the corresponding groove in the member nextThe eccentric openings 32, 33 and 34 are formed in these flangedportions.

C With the openings arranged as described in "the preceding paragraphand with the charging members tightly fitting into one another, as setforth above, it is obvious that the escape of gas from the furnace isimpossible, regardless of the presence or absence of'fuel in thecharging mechanism.

Any suitable means for rotating the ring 19 may be employed. As shown,this intermediate ring extends radially beyond the upper and lower ringsand. on its'periphery "is mounted a ring gear 35 with which 00- operatesa beveled gear 36, operated from "any suitable source of power.

Oil holes or grease ways 38 may be provided for the purposeof admittinglubrica'nts for reducing friction between the bearmg, surfaces of therings 19 and 20, steel rollers S9being also employed, if desired. Ithasfbeen found in practice,however, that the tar and oils distilled fromthe fuel,

when mixed with particles of fuel pulverzed by being crushed betweentherelatively rotating chargingmembers, serve as a very the centralopening 25 after which the top efficient lubricant-and, furthermore,render the charger absolutely gas-tight. j

Any suitable means for deliver ng fuel to the charger may be employed.As shown, a

=hopper 40 is secured to the top ring 20 in any suitable manner, as bybolts 41. The furnace may be initially charged through plate 27 isclamped into position, and a. re-

movable conical cap 41 placed over the whole. Fuel may then be fed tothe pp from a screw conveyor 42 or other suitable lower ring.

means, which delivers coal or the like upon in g member 20:

On rotation of the member 19, fuel is carried in measured amounts froman opening 32 in the upper ring to an opening 33 in the K In thismanner, fuel is continually and evenly distributed to the producer,while at the same time, the esca )e of gas and the entrance of air areeffectively prevented.

In order to prevent caking of the fuel within the hopper 40, plows 43may be provided. As shown, these plows are mounted upon rods 14: whichare bent over the wall of the hopper. The rods may be secured to therotatable ring 19 byany suitable means, as the bolts 15. The plows thusrotate in unison with the ring 19 and serve to level the fuel within thehopper and to prevent any caking thereof. It is apparent that a furtherfunction of these plows may be to distribute fuel within the hopper whenit is found desirable to deliver fuel at one side thereof instead ofover a conical cap, as shown in Fig. 1.
